    Abstract: Various communication systems may benefit from rerouting considerations. For example, fifth generation (5G) systems dealing with radio link failure detection and data rerouting, particularly mmWave 5G systems, may benefit from rapid rerouting methods and systems. A method can include transmitting, from an access point, a downlink control message to a user equipment. The method can also include attempting to detect a Fast-ACK transmission signal from the user equipment in response to the transmitted downlink control message. The method can further include transmitting a rerouting request for the user equipment when the Fast-ACK transmission signal is not detected.

    Abstract: The present disclosure relates to a method performed in a Multipath Transmission Control Protocol (MPTCP) scheduler which is scheduling a TCP flow between a first peer (7) and an MPTCP capable second peer (2). The method comprises setting up the TCP flow comprising at least two sub-flows (8) connecting the MPTCP capable second peer, each sub-flow being associated with an address for the MPTCP capable second peer. The method also comprises receiving external information relating to at least one of the at least two sub-flows. The method also comprises scheduling data in the TCP flow based on the received external information, wherein the scheduling comprises choosing which sub-flow or sub-flows of the at least two sub-flows to schedule the data via, based on the received external information. The present disclosure also relates to an MPTCP scheduler as well as an MPTCP proxy and an MPTCP capable peer comprising such a scheduler.
